Aurora Borealis Alert Service anyone?

Poking around flickr’s hot tags, I noticed that “auroraborealis” and “northernlights” were hot tags in the last 24hrs. It looks from the pictures corresponding to those tags are from Alaska, which is nice for them. I’m frustrated that I’ve been “north” for six years and have yet to see them. I could setup a feed on flickr pictures tagged “vancouver” and “auroraborealis”, but I suspect that will cheerfully let me know about them a day too late. Isn’t there’s a way to get notified when the northern lights are happening (I’d be happy to be woken up!)?
